IMPROVED NAIL-MACHINE.

Specification forming part of Letters Patent No. 103,376, dated May 24, 1870 antedated May 13, 1870.

To all whom it may concern:

Be it known that I, HENRY SGHEUERLE, of New York, in the county and State of New York, have invented certain Improvements in Nail-Machines, of which the following is a specification My invention relates to an arrangement of a fixed frame, between which the pinchers for holding the nail-plate from which the nails are to be cut is arranged, said pinchers being combinedandconnected with suitable mechanism to impart to the forward end of the nailplate the desired motion to produce the required wedge shape of the brad or cut-nail, dispensing thereby with the vibrating of the frame.

My invention consists further, in the arran gement of suitable springs orlevers at the forward end of the fixed frame, between which said springs or levers the forward end of the nail-plate is held fast and guided, and which are operated by suitable levers in such amanner as to move this end of the nail-plate alternately from one side of the machine to the other side, for the purpose of bringing either the one or the other end of the nailblank in the required position to be acted upon by the heading-die after the wedge-shaped strip or blank of metal has been sheared oil".

Figure I is a plan of a nail-machine embodying my invention. Fig. II is a side elevation of part of the machine with the outside of the frame removed. Fig. III is a cross-section of the frame, showing part of the gearing.

Similar letters represent similar parts.

In the accompanying drawings, A represents the main frame, supporting the main shaft B, for carrying the cams to operate the cutter-head O and the guide-bar 0, and to give the required motion to the cutter-head E and the headingdie blocks F F, all of which are arranged and constructed in the usual manner.

Upon the main shaft B a pinion, G, is placed, meshing into a wheel, H, fast on a shaft, J, connected through the bevel-gearing K with a shaft, L, to communicate the desired motion to said shaft L. I

To the end of the main frame A bearings D D are attached, in which the projecting arms of the frame M are supported and fastened. These bearings D D are so constructed that the frame M, when supported by said bearings, may be readily raised or lowered, and moved towardthe one or the other side the same time facilitate the removal of said frame M, to give easy access to the cutters and dies, when required.

' The forward end of the frame M rests upon the frame A, and the after end is supported by the rod S. (See Fig. II.) v

The inner sides of the central part of the frame M are made parallel, and act as guides for a block, N, fitted into the same, capable of sliding freely forward and backward. Into this block N a second block, I is fitted, as well as a bar, Q, capable of sliding or moving sidewise, or at right angles to the frame M.

R is a rod, provided with pinchers It at its forward end, which holds the nail-plate T. The after end of this pincher-rod R is attached to the block P, capable of moving sidewise in said block, and is provided with a projecting pin, a, entering the sliding bar Q, for the purpose of receiving the desired motion from said bar.

The forward end of the nail-plate T is guided by the ends of levers or springs n n, attached to the inner sides of the frame M, and operated by suitable levers, in the manner and for the purpose hereinafter explained.

On the side of the frame M brackets b'b are V attached, upon which the crank-levers V V are centered. The outer ends of these cranks are connected together by a rod, W, to which the sliding bar Q, is attached by means of a ball-joint, d.

Near the lever V the rod WV is connected, through the rod 6, with a crank, X, attached to the end of the shaft L, operated from the main shaft B, as above described.

The crank-lever V is extended below its center of motion, forming a lever, V, (see Fig. II,) which is connected with a bar, to, passing under the frame M, and to which one end of the levers m m are attached. These levers m m turn on centers 8 s, fast on the frame M, and act at their other ends against sliding pins '0 40, passing through the sides of the frame, and which said pins operate the levers or springs 'n a, attached to the inner sides of the frame M, in such a manner as to guide the nail-plate T, held fast betweenthem, and move the same either toward the one or the other side to the headingdie, as may be required.

The operation of the machine is as follows: The revolving crank X will communicate a vibrating motion to the bar or rod W, and consequently a corresponding motion to the sliding bar Q through its connecting-rod d. The forward end of the nail-plate T, being held between the ends of the levers n n, while the after end of the pincher-rod R is connected, through its end pin a, with the sliding bar Q, will receive a vibrating motion toward the one or the other side, producing. a corresponding motion on the forward end of the nail-plate T, in such a manner as to move the same oblique to the face of the cutter-head E before the same cuts off the nail-blank, so as to give thereby the required wedge shape to the brad or cut-nail. At the same time, as shown in Fig. I, the lever V has moved the bar to in such a manner that the lever m has acted against the sliding pin v, forcing thereby the lever or spring at inward, and thereby moving the end of the nail-plate T toward the left-hand side of the machine, so that when the cutter E has sheared oft a wedge shaped strip of metal the same will be in a position for the heading-die F to operate upon the same and complete the nail. The after end of the pincher-rod R is then moved to the other side of the frame, and at the same time the lever m made to act, through the pin 1), against the lever 11, so as to move the forward end of the nail-plate T toward the right-hand side of the machine, reversing thereby the oblique position of the nail-plate, and bringing the next strip of metal sheared off by the cutter in a position to be acted upon by the heading-die F.

To the lower part of the block N a band or chain, y, is attached, having its other end fastened to the end of the frame M, passing over suitable rollers h h, and loaded by a weight, Z, through which arrangement the block N, and consequently the nail-plate T, is moved toward the cutter, bringing the latter under the cutting-shears after each operation.

After each operation the nail-plate T will (which act as a fulcrum for said nail-plate and pincher-rod) and the sliding bar Q will gradually diminish in the same proportion, in con-.

sequence of which the amount of motion communicated to the after end of the pincher-rod R must be diminished in the same proportion, so as to present the nail-plate T always in the same oblique position to the cutter, to obtain a uniform taper to each and every nail. To obtain this object, I make the crank V and the the crank V of different lengths, whereby the amount of motion of the bar W is greatest near the crank V, and consequently the motion communicated to the sliding bar Q and to the end of the pincher-rod B, when near said crank V, and gradually diminishes in the desired ratio (which can easily be regulated by the different lengths of the cranks V and V) as the block N, together with its sliding bar Q, moves toward the crank V after each operation.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The movable block N, by which the forward movement is communicated to the pincher-bar R, in combination with the transverse sliding bar Q, by which the lateral motion is given to said pincher bar, substantially as herein set forth.

2. The arrangement of the slotted block P, sliding block N, transverse sliding bar Q, and pincher-bar R, substantially in the manner and for the purpose herein specified.

3. The arrangement of two cranks, V V, of unequal length, connected by a bar or rod, W, and operated from a rotating shaft, L, in combination with the sliding bar Q, substantially as described.

4. The combination of the levers or springs n n, sliding pins '0 D, levers m m, bar w, and crank-V, operating together in the manner and for the purpose substantially as set forth and described.
